... American). The way in which acid rain is created from here is that About 70 percent of acid rain comes from sulphur dioxide (SO2), which dissolves into the water to form sulphuric acid. The rest comes from various oxides of nitrogen (mainly NO2 and NO3, collectively called NOx). These gases are produced almost entirely from burning fossil fuels, mainly in power satations and road transport. (Kucera, (1973) The Challenge of Ecology, The Mosby Company.) Tremendous quantities of this nitric acid and sulfuric acid mix are reflected in the lowering of the acidity of rain. Earthworms (Annelids) are a species of ...

... look like a scratch. There are also what appear to be old stream channels. This implies that there could have been liquid water on the surface. The surface of Mars is varied greatly between north and south. This has been largely attributed to volcanism and erosion. Mars is similar to our moon in the southern hemisphere. This region is referred to as the “Highlands” of Mars. The area is pitted with numerous craters that reach between one to four km above the datum. Ejecta from the impact scatter around the crater making a rim like structure. The northern hemisphere is very low compared to ...

... blue, green, or pink. One reason why a Diamond has different colors is through the processes involving heat and radiation. Another reason is that 99.5% of a Diamond is Carbon and the rest are different trace elements. These 0.5% of elements are the reason why a Diamond has different color shades. For example Nitrogen causes it to have a yellow tint , and Boron a blue shade. The pink color in some are thought to be caused by deformation of the atomic structure of the diamond crystal. A pure Diamond , which would be 100% carbon, is colorless were created million years ago, when the earth was formed, the materi ...

... found in many different parts of the world. All over Europe and South America there is evidence left behind by the ancient people of these great civilizations.par tab First, a look at whether there is or could be intelligent life on other planets. It is conceivable that we world citizens of the twentieth century are not the only living beings of our kind in the cosmos. Because no alienspar from another planet is on display in a museum for us to visit, the answer, "our earth is the only planet with human beings," still seems to be legitimate and convincing. But that is a very narrow-minded way to look at t ...

... years alone" (Oregon Coast Aquarium). With all the problems in the world with humans and animals, it is hard to see this much money going to help just one whale. There are different types of animal stories that people hear about. There are the wonderful stories about adorable animals that do something amazing or need our help. There are also stories about animals that are used in good and bad experiments. When you hear about the treatment of some animals for research, you feel like forgetting about research. One such story was in 1988, three gray whales got stuck in freezing waters in Alaska, the whales were at ris ...

... Dolly, after Dolly Parton, from an adult sheep (Mario, Christopher). The two share the same nucleic DNA, but differ in terms of their mitochondrial DNA, which is vitally important for the regulation of the cell. The media and the press ignored this fact, and thus claimed that Dolly and her “mother� were genetically identical, which sparked a fury of outcry all around the world. The technique of transferring a nucleus from a somatic cell into an egg cell of which the nucleus had been removed, called nuclear transplantation, is an extension of research that had been ongoing for over 40 years. Up until now, scient ...

... is 24-karats. It is said that gold is so soft in it's purist form that gold bars can be indented by your hands if pressed on. Jewelers often use 18-karat gold, which is three fourths gold. The lower the karat of the gold, the more alloy is in it. An alloy is a metal mixed with another metal to make that metal stronger. This metal is used in many ways including, tooth filling because it doesn't rust away or crack, also it is used for the covering or sealing of an astronaut's helmet. Gold is also a very good conductor of electricity. As you can see, gold is an element that is not only a great gift for someone, ...

... you are in may affect how you develop. For instance, if you have a talent for music, but have no way to acquire instruments, then it is doubtful that you will ever discover your talent with music. Physically, you may have great potential as a runner, but, if you do not get enough to eat, then it is doubtful that you will ever live up to your potential. Traits such as what you look like are inherited from your parents. Your potential is also inherited from your parents. Chromosomes contain the information of a person's potential height, potential strength against disease, and other physical character ...

... we have developed the following overall market analysis: Digital Imaging Conversion Services Much to the dismay of many in the business world, the arrival of the "paperless office" has been slow coming. Even though the technology exists to almost eliminate paper documents, many businesses have never heard about it. This technology is collectively known as Document Imaging. Imaging has evolved out of the necessity for businesses to manage the ever-increasing amounts of information(Porter- Roth Associates, 1996). The following statistics are evidence of the massive amounts of paper that exist in American bu ...

... conglomerate of ices and dust. Major proofs of the snowball theory rest on various data. For one, of the observed gases and meteoric particles that are ejected to provide the coma and tails of comets, most of the gases are fragmentary molecules, or radicals, of the most common elements in space: hydrogen, carbon, nitrogen, and oxygen. The radicals, for example, of CH, NH, and OH may be broken away from the stable molecules CH4 (methane), NH3 (ammonia), and H2O (water), which may exist as ices or more complex, very cold compounds in the nucleus. Another fact in support of the snowball theory is that the best-obs ...
